Transparent purple Fluorite crystals covering the front face with white Calcite crystals covering the backside. The Fluorite are very bright and transparent with a 'wet' luster. The crystals have bevelled edges and darker purple zones on the corners.

Well crystallized specimen of transparent Wulfenite, orange Mimetite, and white Barite blades. This is a floater, or nearly one, well crystallized all around with little to no damage. Comes with a couple old labels including an 'Ordway's Minerals'.

Purple Herderite crystals to 2cm atop platy Siderite crystals, all over Albite. Comes with an old Roberts Minerals label.

Cluster of thick blue Aquamarine crystals with a 3cm pink Apatite crystal, along with minor amounts of Muscovite and Quartz crystals.

Cluster of long Brazilianite crystals to 5cm in an attractive arrangement. Comes with an old Alvaro Lucio label.

Numerous glossy black Neptunite crystals on white Natrolite. Thick crystals to over 2cm long.

Transparent Wulfenite crystals with bright red/orange Mimetite crystals attached.  This is a contemporary classic Wulfenite from the series of pockets found in 1972-1974 that are considered the finest Wulfenites to ever come from the San Francisco mine. The main crystal in this specimen is more stout than the typical more fragile crystals from the mine. Color is mind blowing! Has a small plastic stand attached to the back to hold it upright for display.

Cluster of lustrous smoky Quartz crystals (old labels refer to them as 'Crocodile Quartz'), with one crystal of the rare pseudocubic habit. The pseudocubic crystal is 3cm.

A 2.5 cm wide cluster of Limonite after Pyrite crystals on a typical pegmatitic mound of Feldspar and Smoky Quartz crystals. Out of an old collection with no further locality information. Unusual.

Thick layer of Chrysocolla (?) wrapping around Quartz upon which grow numerous pristine Liroconite crystals. The Liroconite reach 6mm in size and are present on both the top and bottom of specimen and are of the less common blue/green color. From the type locality for the species, likely found in the mid 1800s. Despite it's age and there being dozens (a hundred?) crystals, I can find no damage.
